 ## Troubleshooting
 
 ### Python package installation failure
 
 The Python package installs require `gcc` and `gcc-c++`, which you may need to
-install if you’re running a slim version of Linux (e.g., CentOS).

-CentOS:
-
-```console
-yum -y install python3-devel
-yum -y install gcc-c++

-Debian/Ubuntu:
-
-```console
-apt install -y python3-dev
-apt install -y build-essential

-Alpine:

-```console
-apk add python3-dev
-apk add build-base

 ### gRPC Connectivity
 
 To debug Python gRPC connectivity issues, set the following gRPC debug
 environment variables:
 
-```console
+```sh
 export GRPC_VERBOSITY=debug
 export GRPC_TRACE=http,call_error,connectivity_state
-opentelemetry-instrument python <your_app>.py
+opentelemetry-instrument python YOUR_APP.py
 ```
